MACHINE AND METHOD FOR USE IN SHAPING UPPEBB.

Application filed April 22, 1922. Serial No. 556,068.

This invention relates to the shaping of upper materials in the manufacture of boots and shoes. It is one important object of the invention to provide a method and machine for use in the manufacture of a type of shoe in which the upper is secured in lasted relation to the insole by adhesion, and the invention is accordingly illustrated herein in its application to the manufacture of such shoes, for example tennis shoes or sneakers, and more particularly as applied to the pulling over and lasting of the forepart of the shoe. It will he recognized, however, that in many of its important novel aspects the invention is not restricted in utility to the manufacture of shoes of this particular type. nor limited to combined pulling-over and lasting machines or methods nor to operations performed upon the forepart of the shoe.

Among its important features, the invention provides a novel organization of means for wiping an upper heightwise of the last (i. e... upwiping the upper) and for laying its margin inwardly over the bottom of the last. the machine herein shown having automatic means for upwiping the upper as the overlaying means moves toward the shoe. In the application of the invention to toe end lasting. the machine illustrated comprises in its organization a toe wiper support which is moved toward the toe and carries wipers for laying the margin of the upper about the too inwardly over the sole or insole {hereinafter frequently termed for convenience the sole"), and a toe embracing wiping device or band which embraces the upper about the toe and is operated by the movement of the wiper support to wipe the upper heightwise of the too. It is a further advantageous characteristic of the construction herein shown that the wiping of the upper heightwise of the last is completed prior to any substantial movement of the overlaying means inwardly over the bottom of the last, after which the upwi ing means holds the upper against the lateral periphery of the last during the overlaying operation.

A further feature of the invention consists in a novel organization of means for pulling an upper over-a last, for wiping the upper heightwise of the last and for laying the margin of the upper inwardly over the bottom of the last. In its embodiment of this feature, them'achine herein shown comprises means for performing upwiping and overlaying operations on the upper in time relation to each other after the upper has been pulled. and means for releasing the upper from the upper pulling means in time relation to the upwiping operation. For the urposes of toe end lasting, the machine illustrated has automatic means for embracing and clamping the upper about the toe and for then releasing the toe gripper from the upper, after which the upwiping and overlaying operations are performed in time relation. It is one of the objects of the invention to operate upon the shoe without any substantial overdrawing movement of the toe gripper, such as has been effected heretofore in machines of the illustrated type by movement of the wiper carrying front arm toward the toe. in order to avoid danger of forming folds in the margin of the upper of undesirable prominence at the corners or sides of the toe. and a further feature of the invention is to be recognized in means for accomplishing this object, the construction shown comprising means for releasing the toe gripper from the upper prior to any substantial movement of the front arm to carry the wipers toward the toe.

In the lasting of shoes of the type which includes a comparatively flexible insole of rubber composition and in which the margin of the upper is secured to the insole in the lasting operation by adhesion, it is necessary to guard against wrinkling or displacement of the insole by the lasting pressure and also against adhesion of the margin of the upper to the insole premature] or before the upper has been conformed tightly and smoothly to the last and the insole along the edge of the shoe bottom. For the purpose, among others, of dealing satisfactorily with such conditions, the invention in a further important aspect provides a novel method and a novel machine organization whereby lastin operations on the shoe are performed by t e aid of a flexible apron in engagement with the upper materials. As applied for exam le to toe end lasting, and in accordance wit the illustrative ractice of the method, a flexible apron em racing the upper about the toe is utilized both for wiping the upper heightwise of the toe and for gathering and laying the margin of the upper inwardl over the sole or insole. By reason of its exibility the apron conforms the upper closely to the contour of the last, and by its use the margin of the upper is bent inwardly and pressed into adhering relation to the sole while the upper is held tightly and smoothly conforme to the contour of the sole along the edge of the last bottom and without dan er of displacing the sole or of pressing the margin of the upper into adhering relation to the latter prematurely such as has been encountered heretof re in the use of wipers directly engaging the upper. For better insurance of adequate upwiping pressure, and to assist in holding the upper during the subsequent or erla mg operation, the apron may be pressed inwardl against the upper, for example by clamping it about the toe as herein shown: and in further accordance with the piactice herein illustrated the apron is pulled heightwise of the last in the upwiping operation and is held by its opposite ends while pressure is applied between its ends to f y tin. nungin of the upper over the sole. roned results, moreover, are secured by use of an elastic apron, for example rubber, which as herein illustrated is "etched to increase its frictional drag on ineupper in the unwiping operation and is held in stretched condition as pressure is a plied between its ends to lay the margin oi the upper inwardly. thus further insuring that the upper will be tightly and smoothly conformed to the last and the sole along the edge of the last bottom.

The above and other features of the invention. including novel gripper releasing mechanism together with certain details of construction and combinations of parts, and also the novel method aspects of the invention, will now be more particularly set forth by reference to the accompanying drawings and pointed out in the claims.

The invention is herein illustrated in its application to a well known type of pullingorer machine organization, the general fea tures of which are shown and described in United States Letters Patent No. 1.829.387, granted on June 11., 1312 upon an application of i hiicheeiy. to which reference may be made for a better ui'iderstanding of such details of construction as are not hereinafter particularly described. Machines of this type include in their general organization a toe gripper 2 and opposite side grippers 4 connected respectively to gripper levers 6 and 8 which are operated by cams on a cam shaft 10 to grip and pull the upper yieldingly through tcnsioning springs one of which is seen at 12 in Fig. 1. In the construction shown (Figs. 2 and 10) the toe gripper comprises jaws 14 which are curved for engagement with the upper round the end of. the toe, and the side grippers (Figs. 6 and 7) comprise jaws 16 for pulling the upper at the opposite sides of the forepart at the rear of the toe end. It will be understood that the shoe is positioned initially in engagement with a sole rest (Fig. 2). to be hereinafter more articularly described, with the margin of tie upper within the open jaws of the toe and side grip ers. In the usual operation of machines 0 this general type the cam shaft 10, upon the starting of the machine, makes a partial revolution to cause the grippers to close and to pull the upper and then comes to rest with the upper held under tension to permit any adjustment of the upper which may be necessary by manipulation of one or more of the grippers. It is contemplated that the machine herein shown also may operate in this manner, although the features of the invention may be embodied in a machine having a continu- Lift fi l

ticularly described hereinafter.

ous cycle of operations. In the upper pulling stage of the cycle the sole rest receives a short downward tipping movement from a cam 18 on the shaft 10, and a heel rest 20 is moved forwardly into supporting engagement with the heel end of the shoe.

When the machine is again started, opposite side clamping and supporting devices 22 (Fig. 6) are moved inwardly into operative relation to the .shoe by the action of side clamp arms 24 at the opposite sides of the shoe, and either immediately thereafter, or after a subsequent pause in the'cycle of the machine as predetermined by the particular type of starting and stopping means which is utilized, the margin of the upper is laid inwardly over the sole about the toe and at the sides of the forcpart and is fastened to the sole. The devices for overlaying and fastening the margin of the upper at the toe end and at the sides of the forepart are carried respectively by a front arm 26 and opposite side arms 28 which are swung inwardly toward the shoe by connections to a rearwardly movable slide 30 which serves also through well known means to cause the opposite side grippers 4 to draw the margin of the upper inwardly over the sole, the side grippers being tripped to release the upper by engagement of mechanism on the arms 28 with latches 32 (Fig. 6) on these grippers. In the machine herein shown the toe gripper also is tripped automatically to release the upper in a manner which wlll be more par- After the upper has been laid inwardly over the sole and has been pressed into adhering relation to the sole, as will also be hereinafter set forth in detail, the parts of the machine are returned to their starting positions and the shoe is released.

For purposes of the present invention the machine herein shown is provided with means for embracing the toe of the shoe 5 and for wiping the upper heightwise of the toe toward the edge of the sole before its margin is laid inwardly over the bottom of the sole, such means comprising a flexible wiping device or apron 34 which in the construction shown consists of a sheet of elastic material, such as vulcanized rubber, of suitable thickness to render it durable for the purposes in view and of a width to extend continuously round the toe from one side of the toe to the other. The apron 34 is secured at its upper end to a curved holder or support 36 mounted on arms 38 which are pivoted at 40 on opposite sides of a supporting plate 42 fast on the front arm 26. At its lower end the apron 34 is connected to a further support or clamping device which serves to press the apron inwardly about the toe comprising a chain-- like arrangement of links 44 jointed to gether and arranged to extend for a considerable distance heightwise of the toe and to extend also continuously round the toe from one side of the toe to the other. For supporting and operating the chain 44 the front arm 26 has thereon a carrier comprising a casing 46 provided with trunnions 48 which are mounted in lugs 50 secured to the plate 42. Housed within the casing 46 by means of a cover plate 52 on the lower side of the casing is a slide 54 which at its front end has a cross-arm 56. ()n the opposite end portions of the cross-arm 56 are pivotally mounted supporting arms 58 to which the opposite ends of the chain 44 are connected. A tension spring 60 connected to rearward extensions of the arms 58 tends to swing the arms in directions for straightening the chain, the spring thus afl'ording resistance to insure adequate pressure of the chain and the flexible apron against the end of the toe as they are wrapped about the toe. Midwa between its opposite ends the chain 44 is urther supported and controlled by a slide 62 to which the middle links of the chain are pivoted, this slide being mounted upon the top of the main slide 54, as shown in Fig. 8. Carried by the slide 62 is a pin 64 which projects within a slot 66 in the slide 54, this pin and slot arrangement permitting limited relative movement between the slides 54 and 62 in the direction of the length of the shoe and limiting forward movement of the slide 62 under the influence of the spring 60 when the parts are in their idle positions. In the construction shown the apron 34 is suitably fastened to the chain supporting members 58 and 62, as by screws 67. It will be evident that the apron serves as a facing for the chain 44, the chain and adjacent parts of the apron constituting what may be termed a toe band for embracing and clamping the upper about the toe and for wiping it heightwise of the toe.

For applying the chain 44 and the apron to the shoe there are provided springs 66 which for the greater portion of their length are housed within the slide 54 and hear at their outer ends upon adjusting screws 70 mounted in an upturned end portion of the cover plate 52. The slide 54 is arranged to be held in retracted position, as indicated in Fig. 2, by a latch 72 which is slidably mounted in a boss 74 on the casing 46 and is pressed downwardly by a spring 76 into position for engagement with an end of a plate 78 which is fast on the slide 54 in line with the slide 62. In this position of the parts the toe hand parts are retracted from the shoe and the springs 68 are under compara tively high compression.

The machine herein shown is so constructed as to apply the flexible apron, or toe band, to the shoe substantially at the beginning of the second stage of the cycle as the side clamp arms 24 are swung toward Ill lull

the shoe and while the toe and side grippers are holding the upper under tension. Such application of the band to the shoe is effected by the springs 68, when permitted by retractive movement of the latch 72, the springs then projecting the slide 54, together with the chain and the lower part of thc apron 34, forwardly toward the toe of the shoe. pressure being applied first at the end of the toe and the apron then being wrapped about the too by the movement of the slide 54 and the arms 58 relatively to the supplemental slide 62. Movement of the latch 72 to release or trip the slide 54 is efl'ected in the construction shown by the action of a cam operated slide 80 (Fig. 1) which in machines of the type illustrated serves to swing the side clamp arms 24 inwardly toward the shoe. For operating the latch the slide 80 carries a lug 82 in which is formed a slot 84 to receive the end of a link 86 provided with a shoulder 88 to be engaged by the lug as the slide 80 moves toward the right (Fig. 1) to operate the clamp arms. The link 86 is connected to one arm of a bell-crank 90 the other arm of which is connected by a link 92 to an arm 94 fast on a rock shaft 96 on the rear portion of the frame of the machine, this rock shaft having fast thereon another arm 98 which is connected by a link 100 to a tripping member 102 pivotally mounted on a holder 104 on the frame. The member 102 has a forwardly projecting arm which is forked to embrace the upper end of a rod 106, the latter being pivoted at its lower end to the upwardly extending shank of the latch 72. Near its upper end the rod 106 has a shoulder 108 which is enaged by the member 102 to impart upwar movement to the rod 106 to withdraw the latch from engagement with the plate 78 when the member 102 receives its operative movement from the cam slide 80. As will be evident by reference to Fig. 3, the tripping member 102 in its continued movement slips from engagement with the shoulder 108 and thus releases the rod 106, permitting the spring 76 to return the latch 72 into latching position as soon as permitted by relative movement of the parts at a later time in the cycle.

In the position which the toe band assumes in response to the action of the springs 68, as illustrated in Fig. 4, the band is wrapped completely about the toe, the springs 68 acting with suflicient force to hold the upper from relaxing when it is released by the toe gripper. In the machine herein shown there is provided means for tripping the toe gripper automatically to cause it to release the upper at a considerably earlier time in the cycle than has been the practice heretofore, and prior to any substantial movement of the front arm 26 toward the toe, thus avoiding any substantial rearward over-drawing movement of the toe gripper with the consequent tendency on shoes of the class herein shown to form in the margin of the upper pleats of undesirable prominence at the corners of the toe. For the purposes in view the toe gripper in the construction shown is tripped immediately after the toe band is applied in holding engagement with the upper, and by a part of the same means whereby the latch 72 is operated. The connections for effecting the tripping of the gripper comprise an arm 110 on the rock shaft 06, to which is connected one end of a rod 112, the other end of the rod being mounted slidingly in a socket formed in a sleeve member 114 (Fig. 10) pivoted on an arm 116 which is fast on a forked member 118 rotatably mounted on a bracket 120 on the frame. The member 118 is connected by a universal joint to a rod 122 which telescopes within and is keyed to a member 124. the latter being connected by a universal joint to a tripping member 126 which is pivoted on the side of the toe gripper casing by means of a screw stud 128. The member 126 is provided with a finger 130 which is arranged to engage the usual latch member 132 whereby the toe gripper jaws are tripped to cause them to release the upper. A spring 134 tends to hold the member 118 and its connected parts, including the tripping member 126, in idle position, but permits the parts to be operated by the rod 112 to press the latch 132 inwardly. Between the rod 112 and the sleeve member 114 there is provision for sufficient lost motion to insure that the toe band will be applied firmly about the toe in upper holding position before the toe gripper releases the up er.

fter the toe band has been applied about the toe and the toe gripper has released the upper, the next operation of the machine is to wipe the upper 11 wardly toward the edge of the sole to contbrm it smoothly and tightly to the contour of the last without objectionable wrinkles in any art which is visible in the finished shoe. he upwiping operation is effected bybodily upward movement of the toe band chain 44 and of the a ron 34, accompanied by an upward stretc ing of the. elastic apron to increase its frictional drag on the up er. These operations are accomplished y a swinging movement of the carrier 46 about the axis of the trunnions 48 and an accompanying movement of the arms 38 about the pivots 40. the movements of these parts being effected in response to the swinging movement of the front arm 26 toward the shoe. swinging the carrier 46 there are pivoted on studs 136 at opposite sides of the plate 42 arms 138 which are provided with cam extensions 140 in engagement with the carrier 46. At their upper ends the arms 138 carry For [ill

adjustable bearing screws 142 which are arran ed to engage the front face of a hearing lock 144 fast on the .frame of the machine. A sprin 146 which is connected at its opposite en s to said block and to the carrier 46 serves to hold the carrier against the cam members 140.

Swinging movement of the arms 38 to lift the apron holder 36 is effected b cam plates 148 which are secured to the b ock 144 and have edge faces engaged by rolls 150 on the arms 38. To hold the rolls against the cam plates, springs 152 are connected to the arms 38. As the front arm 26 is swun toward the shoe the toe baud chain 44 and t e apron 34 are thus lifted bodily, with the a ron in wiping engagement with the upper a out the toe, the chain yielding as required to maintain the apron in close conformity to the shape of the toe. The support 36 for the upper end of the apron receives a greater upward movement than the chain and thus acts to stretch the elastic apron and thereby to increase the frictional drag of the apron on the upper as well as to assist in holding the upper tightly in conformity to the contour of the last. As this upwiping action is taking place the upper portion of the apron is carried forwardly by its support 36 to bring the apron in to e ective engagement with the upper substantially at the edge of the sole, the parts assuming at the end of the upwiping operation substantially the positions illustrated in Fig. 5.

The gathering and overlaying of the margin of the upper about the toe 1S effected by the action on the apron 34 of toe embracing wipers 154 which are mounted on a carrier plate 156 (Fig. 9) for swinging movement laterally of the shoe about axes afforded by pivot studs 158, the wipers being hinged together and provided with wiping edges which extend continuously about the toe from one side of the toe to the other side. Since the manner'in which these wipers are mounted is substantially as illustrated in Letters Patent No. 1,541,820, granted upon my application on June 16, 1925, it need not be further described in detail. For overlaying the upper at the sides of the forepart at the rear of the toe end the machine is rovided with wipers 160 (Figs. 6 and 9) wliich have upturned inner ends to guide them over the edge of the shoe bottom and are secured to supporting arms 162 mounted on pivot studs 164 winch are secured to the outer ends of supporting members 166 fast on plates 168 on the side arms 28. The members 166 with the wipers 160 are adjustable laterally of the shoe along guideways formed in the plates 168 and are held in adjusted position by clamping bolts 170.

For depressing the arms 162 the plates 168 carry plungers 172 which are mounted in blocks 174, the latter having therein springs 176 which bear downward] on the lungers and hold them normally at their lowgr limits of movement determined by en agement of their flanged heads with shoul lers on the blocks 174. Light springs 178 connected to the arms 162 and to the plates 168 hold the arms 162 upwardly a 'nst the plungers 172, and the arms 162 wit their wi rs are thus positioned preferably to wipe t e margin of the upper in over the bottom of the sole with comparatively light pressure upon the sole so as to avoid danger of displacing the marin of the sole in the overwiping operation.

n such overwiping operation the wipers may yield upwardly a ainst the pressure of the spring lun rs 1 2 in res onse to resistance of t e s oe materials. E means of screw and slot connections 180 ig. 1) the blocks 174 with their plungers 172 are alljustable on the plates 168 in order to osition the wipers relatively to the plane 0 the shoe bottom to apply to the upper the degree of pressure desired.

To close the toe embracing wipers 154 laterally of the shoe in their movement len hwise of the shoe, the arms 162 u on w ieh the side wi ers 160 are mounte are provided with orwardIy extending fingers 182 (Fig. 9) for engagement with upwardly exten ing projections 184 on the ends of the wipers 154. It will be understood that in the movement of the front and side arms 26 and 28 inwardl toward the shoe the projections. 184 on t e toe wi ers are carried into position to be engage by the fingers 182 by the time when the wipers arrive substantially at the edge of the shoe bottom, and that in the continued movement of the wipers 154 lengthwise of the shoe they are closed inwardly by the fingers 182, simultaneously with the overwi ing of the margin of the upper at the rear of the toe by the action of the side wipers 160. It. will also be observed that the side wipers 160 have forward extensions beyond which the toe wipers advance, the toe and side wipers thus assuming what may be termed an interlocking relation to insure a continuity in the overla ing action of the different wipers upon is e margin of the upper materials.

As hereinbefore explained, the athering and overlaying of the margin of t e a per about the toe end of the shoe is efiecte by the action of the toe embracing wipers 154 upon the elastic a ran 34. The wipers arrive at the edge 0 the shoe bottom substantially at the time when the upwipin of the upper about the toe is completed. order to prevent any further upward movement of the toe hand during the overlaying o eration of the wipers, the casing 46 is provi ed with depressions 186 to receive the ends of the cam extensions 140 and permit the extensions to turn idly in contact with the casin without swinging the casing about its pivotal axis during continued forward movement of the front arm 26. Preferably also the cam plates 148 are so shaped as to impart no further upward movement to the apron holder 36 during the overlaying of the margin of the u per, the lower ortion of the edges of sai plates, beyond t e point indicated at a, being substantially concentric with the axis of swingin movement of the front arm. It will be evi ent, however, that the upper portion of the apron 34 is carried inwar y over the bottom of the shoe by the member 36 durin the overlaying of the wipers, suc movement 0 portion of the apron bein continuous throughout the movement of e front arm 26, with the result that the apron, while held in its stretched condition, is drawn inwardl against the upper at the edge of the so e and is wrapped about said edge to bend the margin of the upper inwardly over the sole. As t e toe wipers in their advancing and closing movements become effective upon the apron, they accentuate the over-wrapping or overlaying eifect of the a ron and press the apron inwardly at the si es of the toe, the wipers actin also to stretch that portion of the apron w ich is in engagement with the upper about the toe, thus rendering the apron further effective to draw the u per snioothly and tightly over the edge 0 the so e.

Similarly to the side wipers 160, the toe wipers 154 are so positioned relatively to the lane of the sole as to apply comparative y little downward pressure upon the sole in their inward movement, so as to avoid dan er of displacingl the sole on the last and ago of ressing t e margin of the upper premature y into position to adhere to the sole. After the toe wipers and the side wipers have completed their inward movement over the shoe, they are forced downwardly to press the mar 'n of the u per firmly into adhering ation to t e sole. The downward movement of the toe wipers is effected by the action of a presser bar 188 on the front arm 26, the wipers being supported for the purpose of such movement upon a swingin holder 190 pivoted on the plate 42, and t e ownward movement of the side wipers is effected by premer bars 192 on the side arms 28 the several resser bars being operated and controlled in substantially the same manner as the tack driver bars of rior machines of this general type. It will he understood that the downward movement of the presser bars is effected by the action of spring impelled arms 194 (Fi 1), the resser bars being normally uph d by the s 1de and its connected parts which at the end of the inward movement of the front and side arms are rendered operative to release the bars. The controlling means for the front presser bar is shown in Fig. 2,

operation the upper and comprises a block 196 on the presser bar which is engaged by a shoulder 198 on the shde 30. Fig. 3 illustrates the ositions of the parts when the shoulder 198 as released the lock 196 upon movement of the slide 36 relatively\ to the front arm, such action in the mac ine herein shown resulting from the engagement of a block 200 on the front arm with a stationary abutment 202 which limits the swinging movement of the arm. It will be understood that the side resser bars are similarly controlled, the inward movements of the side arms 28 being limited by abutments 204 (Fig. 6). When the front and side resser bars are thus released, they are forced yieldingly downward by the arms 194 and act upon the toe wiper plates 154 and upon the side wipers 160 to press the margin of the upper firmly into adhering relation to the sole. The front resser bar 188 is connected to the wiper hol er 190 by links 206 for depressing and lifting the wipers through the movements of the bar. For depressing the side wipers the bars 192 carry blocks 208 which engage the arms 162 and force them downward, the arms being subse uently returned by the springs 178. It wi I be understood that in the return of the parts to starting position the front and side presser bars are lifted by the action of the slide 30 and its connected parts in substantially the same manner as the tack driver bars of prior machines, thus relieving the pressure of the wipers upon the shoe before the wipers are swung outwardly away from the shoe.

In order to avoid any danger of relaxing the pressure on the shoe when the slide 30 receives its movement relatively to the front arm 26 to release the resser bar 188, whereby the well-known yielding wedge connectlons between the slide and the front arm are rendered less effective to hold the arm in its inner position, the machine is provided with supplemental means for applying inwardly directed pressure to the arm 26. For this pur se there is pivotally mounted at 210 on tli arm 26 a carrier 212 which has therein a sprin plunger 214 arranged to hear u on the out face of the arm, and the sli e 30 carries a roll 216 which bears upon a curved bar 218 secured on the side of the carrier 212. Since this su plemental pressure applying means is en stantially like what 1s shown in Letters Patent No. 1,648,403, granted on my application on November 8, 1927, it need not be further described in detail. It will be understood that through this means adequate holding pressure upon the arm 26 is insured to maintain the wipers at the inner limit of their overwiping movement when the wipers are forced downwardly to press the upper upon the sole. Such supplemental holding means for the arm is particularly useful in the present machine in view of the resistance of the elastic apron 34 a ainst the wipers.

As shown in Fig. 11, t e sole rest comprises a pair of sole engagin feet 220 arranged to engage opposite si e portions of the sole at the rear of the toe end and a third foot 222 for engaging the sole nearer the toe end of the shoe, the several feet being supported upon a carrier 224 Fig. 3) which, as hereinbefone explaine 1s rocked downwardly in the upper lpulling operation by the ram 18. It has een found that in operatin upon shoes of the type illustrated there is a tendency in the upper pulling operation to wrinkle the soft and yielding sole by the pressure of the several sole rest feet upon the sole. In the present construction there is accordingly rovided means for straightening the sole y relative movement of the sole rest feet. To this end the side feet 220 are mounted on the front ends of arms 226 which are mounted in turn on pivot studs 228 in a bracket 230 which is fast on the carrier 224 (Fig. 3), and the front foot 222 is supported on a holder 232 which is mounted in the carrier 224 for sliding movement lengthwise of the shoe relatively to the bracket 230. A spring 234 tends as in prior constructions to move the holder 232 rearwardly, and for moving the holder forwardly against the resistance of the spring a pinion 236 is provided in engagement with rack teeth 238 on the holder, the pinion being fast on a shaft to which is secured a hand lever 240. Secured to the holder'232 is a plate 242 provided with a pin 244 which engages in slots 246 in the rear ends of the arms 226 and acts, when the holder is moved forwardly, to swing said arms in directions to separate the side feet 220. It will be evident therefore that by movement of the hand lever 240 after the machine has come to a stop with the upper under tension the front sole engaging foot 222 is moved forwardly toward the toe and the side feet are simultaneousl moved apart toward the sides of the last to 1nsure that the sole will lie fiat upon the bottom of the last at the forepart.

In order to hold the sole engaging feet in the position to which they are moved by the hand lever 240, the shaft which carries the pinion 236 is provided (Fig. 12) with a ratchet wheel 248 which is en aged by a pawl 250. In order to cause t e sole rest feet to be returned automatically to starting position by the action of the spring 234, the

aw] 250 is controlled by a releasing membe! 252 carried by a slide 254 whereby, in machines of the illustrated type, the heel rest 20 is moved forwardly into engagement with the shoe. It will be understood that in the first period of the cycle the slide 254 is moved into position to permit the pawl to engage the ratchet wheel, and that in the latter part of the final eriod of the cycle the slide is returned and renders the member 252 operative to swing the pawl into position to release the ratchet wheel, as shown in Fig. 12.

The means above described for straightening the sole by relative movement of the sole rest feet is not claimed herein, but in a divisional application Serial No. 184,394, filed on April 16, 1927.

In the operation of the machine, summarized, the operator presents in the position illustrated in Fig. 2 a shoe, for example, of the type hereinbefore referred to, having the margin of its upper coated with cement, and then starts the machine, whereupon the toe and side grippers are closed in the well-known manner and pull the upper over the toe and the opposite sides of the forepart of the last. If controlled in the manner customary heretofore in machines of this general type, the machine will then come to a stop with the upper held under tension, permitting the operator to inspect the work for any adjustment which may be necessary. During this pause in the cycle of operations the operator may, if the character of the work renders it desirable, move the lever 240 to spread the sole rest members and thus insure that the sole will lie flat upon the forepart of the last. Upon the subsequent starting of the machine, the side clamps are swung inwardly into engagement with the shoe, and simultaneously the spring mechanism for applying the toe band chain 44 and the flexible apron 34 about the toe is tripped by the latch 72. Immediately upon the application of the band about the toe and before any substantial movement of the wipers 154 toward the shoe, the toe gripper is tripped to release the upper. Following this operation the front and side arms are swung inwardly toward the shoe, the front arm acting to raise the band chain 44 and the apron 34 to wipe the upper about the toe and at the same time to stretch the apron to increase its frictional drag on the upper. The upwiping movement of the apron ceases substantially at the time when the apron is in the position illustrated in Fig. 5, the wipers 154 having then advanced substantially to the edge of the shoe bottom, and by continued movement of the front arm 26 the wipers are forced rear wai'dlv over the toe in engagement with the flexible apron while the apron is held in stretched condition by its supporting member 36, the latter moving rearwardly with the wipers to draw the apron inwardly over the shoe bottom.

Simultaneously with the movement of the front arm toward the shoe, the side arms 28 are swung inwardly and operate the side wipers 160 to lay the margin of the upper over the sole at the sides of the forepart,

till

the side grippers being tripped to release the upper by the inward movement of the arms. As the side wipers are thus moved inwardly, the fingers 182 engage the projections 184 on the toe wipers and close the latter inwardly over the sides of the toe during their advancin movement lengthwise of the toe. During t eir advancing and closing movements the toe wipers 154 act upon the flexible apron 34 to press it inwar ly from the end and side faces of the toe portion of the last and thus to gather and lay the margin of the upper inwardly over the sole, the wipers operating in such relation to the plane of the sole as to avoid pressing the margin of the upper prematurely into adhering relation to the bottom face of the sole. During this movement of the toe wipers they act frictionally on the elastic apron which is held in stretched condition between the toe band chain and the supporting member 36, and tend further to stretch the apron inwardly from the edge of the shoe bottom, thus tightenin the apron over the edge of the sole and i urther insuring that the upper will be conformed smoothly and tightly to the contour of the last and to the sole alon theedge of the shoe bottom. As the ront arm is thus moved lengthwise of the shoe, the springs 68 apply progressively increasing pressure to the band chain 44 to assist in holding the upper about the periphery of the toe. When the front and side arms have. arrived at their limits of movement, the pressure bars 188 and 192 are tripped, and the toe wipers and the side wipers are then forced downwardly to press the margin of the upper firmly into adhering relation to the sole. After this operation the parts are returned to starting position and the shoe is released.
